Minor Description
The Deltaspike Scheduler runs fine if Quartz is configured with RAMJobStore. But if Quartz runs with JdbcJobstore, QuartzScheduler.registerNewJob() fails (stacktrace below). I think a simple check like
if (this.scheduler.getJobDetail(jobKey) != null)
would already help.
Caused by: org.quartz.ObjectAlreadyExistsException: Unable to store Job : 'DEFAULT.PastDueScanJob', because one already exists with this identification.
